例子： <br>
mysql&gt; create table test_tb(id int(1), col2 tinyint(1)); <br>
mysql&gt; insert into test_tb values(256, 257); <br>
mysql&gt; select * from test_tb; <br>

| id | col2 | <br>
+——+——+ <br>
| 256 | 127 | <br>
+——+——+ <br>
说明： <br>
整数的位数限制只是在显示时，如果没有数据中的字符长度不够用0补充。</p>                                    </div>
